SPECIFICATION forming part of Letters Patent No. 698,351, dated April22, 1902.

Application filed March 20, 1901.. Serial No. 51,999- (Il'omodel-lcation.

My invention is an improvement in rollerbearings specially designed fora thrustbear: ing; but the manner of holding in the rolls is capable ofuse in many different situations.

In the accompanying drawings, Figure 1 shows a face view of athrust-bearing, and.

Fig. 2 is a sectional view of the same. Fig. 2 is an enlarged detailshowing the end of the rollerand its containing-slotof Fig.2. Fig. 3shows a modification. Fig. 3 is an enlarged detail of the roller andcontaining-slot of Fig. i

3. Fig.4 shows another modification. Fig. 5 shows a modified method ofholding in the roll, and Fig. 6 shows a detail of construction.

In carrying out my invention I provide what I may term a cage in theform of a disk having an open center and a series of slots radiatingfrom the open center. The Walls or faces of the disk taper inwardlytoward the center, and the slots are also made tapering, their smallerends being at their inner extremities, where they merge into the opencenter,and their broader ends being at their outer extremities. The diskis shown at A, the open center at B, and the radiating slots at C. Toobviate the making the cage of tool-.

steel, a pin a, hardened and ground, is inserted at the head of eachslot to form a hearing for the end of the roll.

The slots 0 are cut with straight walls, and the rollers b, which aretapering, are inserted, and in order to hold them in place I apply toeach side of the cage alight sheet of metal, these sheets beingidenticalin form with the cage, but having the slots therein of slightly lesswidth, so that they overlap the slots in the cage sufficiently to holdthe rolls in place and prevent their displacement. These sheets areindicated at D and are riveted or other- I make the cage A in two piecesand make the slots of varying widths, so that upon the outer face of thesections of thecage the width of the slots will be sufiicient to retainthe rollers in place, While the width of the slots on the inner faces issufiicient to allow the rollers to be inserted. The two sections arethen placed one upon the other and riveted or otherwise secured, andthis makes a self-con- V tained cage. 7

Instead, as in Figs.l to 3, of having the slots run through to thecentral opening I may make a stronger construction by having the slotsintermediate of the cage between the inner opening and the outerperiphery,as shown in Fig. 4:.

In Fig. 5 I show another modification, in

which the slot is first formed with straight walls by punching orotherwise, and thence upon each side of the slot and upon each face ofthe cage the metal is indented to force inwardl'y an overhanging lip, asshown at o,

which confines the roller in place.

What I claim is 1. A roller-bearingcomprising a cage having an intactouter periphery and an open center with a plurality of radiating slotsopening into said center, rollers fitting in said slots, and means forconfining the rollers in the slots, substantially as described. V

2.. A roller-bearing comprising a cage having radiating slots formedtherein, rollers within said slots, said cage having independ-
